Number of bits per pixel of this raster image

Dimap 1.1 Generic Profile

<NBITS>

Dimap_Generic 1.0

Description :

This record provides the number of bits used for each pixel of each band of the raster image.

By default NBITS=8 (a byte). This keyword is used for images which have a DATA_TYPE different than BYTE. This is the case for 16-bit DTM or radar images. It is especially useful with RAW data file format.

Example :
 
<Raster_Encoding>
  <NBITS>16</NBITS>
  <BYTEORDER>M</BYTEORDER>
  <DATA_TYPE>SHORT</DATA_TYPE>
  <SKIP_BYTES>512</SKIP_BYTES>
  <BANDS_LAYOUT>BIL</BANDS_LAYOUT>
</Raster_Encoding>

Datatype : t_NBITS (based on PositiveInt)
